Abstract：Taking Zhuhai cityas an example，this paper conducts research onanaerobic digestion engineering of kitchen waste.Adopting a graded pretreatment process，impurityremovalandoil recovery areachieved through large material sorting，fine pulping，sandandimpurityremoval，and tre-phasecentrifugalseparation.Theehydratedfiltrateandfactory wastewateraredischargedincompliance throughacombinationofcoagulationairflotation，exteral Membrane BioReactor （MBR），andnanofiltration processes，forming aclosed-loop treatment systemof“quality pretreatment—collaborative anaerobic-energy recovery—wastewater purification". The processroute is reasonable and has significant resource utilization benefits.

Keywords： kitchen waste; thermophilic anaerobic digestion; Membrane Bio-Reactor （MBR）
